Once again we have a star-studded cast of voice actors including Martin Sheen, Kristen Bell and Michael York.
You can buy a DVD copy from the company behind the film, or Amazon does stock imported US versions. However, they are quite expensive and will take a little while to arrive.
For those of you who do not want to seek an illegal online streaming copy (which we do not condone here at Maths At) there is always the possibility of reading the book by Edwin A. Abbott, which sticks pretty close to the movie, except for one or two plot points. The book also goes into much more detail about the Flatland universe.
Be there or be square.
